The rear end is in pieces

[87foxstang]

In a good way Due to decent weather today I finally got a start on my traction loc rebuild. I got as far as getting the assembly out and inspecting everything. This was my first time doing any reared work, so i took it slow and i really enjoyed doing it. I never knew what gears I had in the car, but i knew they were not stock. Judging by my rpm's and mph, I thought I had 4.10's but I found out today that I really have 3.55's. I don't know if i am happy or mad Either way, its cool.

Just thought I would share

so then are you going to up it? 3.73's are ****ing nasty, my friend. i love mine. never driven in a car with 4.10's.. i assume it's a blast though!

 

[87foxstang]

Im not sure. If someone wants to make a trade Im surprised that they are 3.55's, the car pulled 1st and second crazy hard, which is another reason why i thought they were 4.10's lol

i agree i think 3.73's are the best choice for a daily driver, I jumped from my stock
2.73's to 3.73' with an eaton posi and superior 31 spline axles and was amazed by the difference

 

[MaxTheHooker]

haha, i wonder what the difference is in the quarter.. how modded was your car before you put the 3.73's in it? do you have any before and after quarter mile times? i bet they'd be interesting!

 

[Mustang5L5]

I would stay with the 3.55's.

I have 3.73's in my car and just bought some 3.55;s They will be going in when i get a chance

Liked the 3.55s in my old car, very nice street gear, nice kick in the ass, driveble on the freeway, milage won't kill ya- 3.73's in mine as big as you'd wanna go for driving, imo. 4.10? Best in somebody elses car, to take up and down the street a couple times, just to feel it. What if it rains, or snows? You ain't goin nowhere. You pulled hard cuz the rest is done right, 3.55s

 

[LiquidGT]

Pulls hard, dont mess with whats proven for your car, stick with the 3.55's.

 

[87foxstang]

Yea Ill be sticking with them. It is a good all around gear. Plenty down low and enough up top.

first and most of 2nd are useless in a stock 86 5.0 with 4.10's

time to change your sig then

 

[92mustanggt509]

i just put 4:10's in with all my mods. i guess im screwed

 

[25thmustang]

With similar mods as him, and 285 tires, 1st and 2nd is more or less useless with 3.73s unless you pedal it, which is simple enough. New England has crappy roads which hurts traction.

If it works I say leave it. My brothers 86 has 3.55s now and has been 12.17 @ 110. He is doing 4.10s so I will let you know what it runs afterwards.

 

[87foxstang]

Yes, i need to change the sig now. So it looks like Ill still be ok at the track when I go. Awesome

 

[87foxstang]

Oh I forgot to add, my pinion shaft retaining bolt is slightly bent. Where can i Buy one of these. Do I need to go to a ford dealer to get it?

 

[87foxstang]

Nevermind, found one
